What is ASTM E119?

What is ASTM E119?

A standard called ASTM E119 provides instructions for ratings and criteria for the fire resistance of various building materials. It guides the work of professional contractors (along with other project stakeholders) in constructing interior spaces.

What is ASTM E2307?

ASTM E2307 measures the ability of the PFB system to maintain a seal and prevent fire spread as the exterior wall assembly deflects and deforms during a fire. The standard simulates a condition where a fire begins in a room near the exterior wall, and a fire plume exits a window opening.

What is ASTM E136?

Standard: ASTM E136 – Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750°C. Certification Required: The International Building Code (IBC) and International Residential Code (IRC) prescribes this test for materials that are required to be non-combustible.

What NFPA 251?

NFPA 251: Standard Methods of Tests of Fire Resistance of Building Construction and Materials.

What is the hose stream test?

The hose stream test was developed in the late 1890s to measure the structural integrity of floor materials and cast or wrought iron in building walls during an intense fire. It was not intended or designed to test the thermal stress performance of glazing materials.

What UL 263?

ANSI/UL 263, the Standard for Safety of Fire Tests of Building Construction Materials, and ASTM E119, Standard Test Methods for Fire Tests of Building Construction and Materials, were developed to simulate a building fire.

What is ul2079?

UL 2079, 5th Edition, August 26, 2015 – UL Standard for Safety Tests for Fire Resistance of Building Joint Systems. These tests are applicable to joint systems of various materials and construction that are intended for use in linear openings between adjacent fire resistive structures.

What is considered non combustible material?

Examples of non-combustible materials include steel, masonry, ceramics and certain insulating materials (such as fiberglass or mineral wool insulation). Gypsum wallboard is considered by the codes to be non-combustible although it does have a thick paper backing that is combustible.

Is there non combustible drywall?

Fireproof drywall is the common term; its industry name is Type X drywall. The thickness of this drywall is 5/8-inch, including all layers. Glass fibers are added to the board to help it retard fire. Also, because it is denser than normal gypsum-and-paper drywall, it takes longer for the fire to degrade it.

What NFPA 257?

NFPA 257, Standard on Fire Test for Window and Glass Block Assemblies prescribes fire and hose stream test procedures that apply to fire window assemblies – including window, glass block, and other light-transmitting assemblies – intended for use in window openings to retard the spread of fire through openings in fire- …

What NFPA 253?

NFPA 253: Standard Method of Test for Critical Radiant Flux of Floor Covering Systems Using a Radiant Heat Energy Source.

What are the hardness of button cap screws?

Metric Button Head Socket Cap Screws-Property Class 12.9 Applicable Standards: ASME B18.3.4M and ASTM F835M. Hardness: RC 38-45. Tensile Strength: 1220 MPa min. Note: Screws of nominal length shorter than those listed in Column L will be threaded to the head. Metric Button Head Socket Cap Screws-Property Class 12.9 (continued)

How does the ASTM E119 fire resistance test work?

ASTM E119 (UL 263): tests the fire resistance of an assembly. This test evaluates the duration for which building construction materials and assemblies can either contain a fire, retain structural integrity, or both. To become one-hour fire-rated, an assembly must withstand fire for one hour before penetration to the other side occurs.

Which is stronger stainless steel or nylon button head screws?

A nylon patch bonded to the threads adds friction to prevent loosening from vibration. Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws.

How big are button head socket cap screws?

Inch Series Button Head Socket Cap Screws (continued) Standard Screw Length Increments Nominal Screw Length Standard Length Increment. 1/8 through 1/4 1/16 1/4through 1 inch 1/8 1 through 2 inches long 1/4. Length Tolerances Nominal Screw Size Nominal Length #2 through 3/8 Tolerance on Length 1/2 and 5/8.
